Introduction Sweetpotato faces breeding challenges due to physiological and genomic issues. Gamma radiation is a novel approach for inducing genetic variation in crops. We analyzed the transcriptomic changes gamma ray-induced sweetpotato mutants with altered stem development compared those wild-type 'Tongchaeru’ cultivar. Methods RNA sequencing analyses were performed identify expression of genes related development. Results Transcriptomic analysis identified 8,931 upregulated 6,901 downregulated genes, including upregulation auxin-responsive SMALL AUXIN UP ( SAUR ) three PHYTOCHROME INTERACTING FACTOR 4 PIF4 genes. crucial regulating early growth Arabidopsis thaliana . In mutant, several elongation, involved various signaling pathways such as auxin gibberellin, upregulated. Discussion Our results suggest that mutations influence auxin-dependent by modulating complex regulatory network involving other gibberellin ethylene This study enhances our understanding mechanisms underlying sweetpotato, providing valuable insights genomics-assisted efforts.
